One of the things I don't like about my SuperDuty is when in tow/haul, or if the exhaust brake is on, if you apply the brakes it shifts down. For this reason I will use manual mode when descending hills and choose the gears myself. This allows me to use the brakes sparingly if needed without reving too high.
Since the braking effect puts a load on the engine and turbo, higher RPM is what you want. A little load each stroke at higher RPM is better than a lot of load each stroke at a low RPM. The engineers knew what they were doing, and second guessing the programming is not in your best interest.
